[1979 Power window repair]

It's been too long ago for me to remember how things go together, and the shop manual isn't much help.

Maybe if you posted some photos it would help jog some folks' minds. How much of the assembly did

you remove... is your mechanism out of the door, or can you see and access the spring with the assembly

still in place?

I vaguely remember taking the entire motor/spring/actuator arm/scissors assembly out of the door to work

on it (I had to replace the motor), but I'm not certain if the window lifting scissors came out with it.... IIRC

I think it did, and I had wedged the (fully up) window at both ends of the door to hold it up before

I removed the bolts from the center pivot and the motor/spring assembly, then the retainers from the

rollers of 3 arms of the scissors mechanism to pop it free it from it's tracks, then it was a matter of

snaking the whole assembly out of the rectangular access hole in the bottom of the door, articulating

various arms to get one part, then the next, etc, until it was all out of the door... not an easy task.

I guess one concept to keep in mind is that the motor needs an assist in raising the window, so I think

the idea would be that the spring be almost fully compressed (wound) when the window is down, almost

fully free when the window is all the way up (scissors actuator arm at the motor/spring assembly moved

towards the rear of the door).

It might help to take the other door panel off to see how the spring is positioned with the window fully up,

and try to visualize the mirror image of that to picture how the opposite door spring needs to look with the

mechanism scissors in that same position. If you spin the motor in a direction to get the scissors actuator

arm as far towards the spring/motor assembly as possible (eg, towards the front of the door), then attach

the spring (and you may have to pull it's end over to the mount pin, slightly compressing it), then reverse

the electrical leads on the window motor to compress (wind) the spring to the position it was in when you

removed the assembly.

Hopefully someone else has a better memory than mine.

Wayne,

I took the complete window assembly out of the door. After laying it out on my work bench, I dicovered that the main (LIFTING) spring was in two pieces. I located a new spring and installed it with the window at the top location (NOT KNOWING THE ORIGINAL POSSISION). The window works but very slow going up. My question is how do you load that spring? Someone must know the procedure. Thankyou for the feedback. Frank
